Creation of a large field emission device display through the use of multiple cathodes and a seamless anode

Abstract

One anode 350 and multiple cathodes 50, 60, 70, and 80 create a large display field emission device. The use of one anode 350 facilitates an image which is seamless to the viewer. The use of multiple cathodes 50, 60, 70, and 80 allows a single image or multiple images to be displayed. The use of multiple cathodes also provides fast refresh rates and a high resolution image. Methods of fabricating and operating the large display field emission device are disclosed.

What is claimed is: 
     
       1. A method of fabricating a large display electron emission apparatus comprising the steps of: providing an insulating substrate;   depositing a conductive layer on a surface of said substrate;   coating said conductive layer with photoresist;   applying a patterned mask over said photoresist and developing said photoresist to remove selected portions of said conductive layer;   removing any remaining photoresist;   mounting at least two emitter plates to said substrate;   sealing one anode to said emitter plates;   mounting row and column drivers on said conductive layer;   bonding electrically conductive interconnects between said emitter plates and said row and column drivers;   providing an electrical connection between said row and column drivers and control circuitry.
